Awesome Codex & ChatGPT Plugins

A curated list of awesome plugins, skills, and resources for OpenAI Codex and ChatGPT.

OpenAI documents plugins and skills for Codex, packaging skills, MCP servers, and app integrations into shareable, installable bundles across the Codex app, CLI, and IDE extensions.

Codex is now available inside the ChatGPT desktop app, while remaining a distinct coding workspace. OpenAI plugins can support workflows in ChatGPT, Codex, or both; this repository remains a Codex-compatible marketplace.

New plugin workflow:

1. Create with $plugin-creator 2. Validate with plugin-scanner. The catalog-owned centralized scan must report a numeric score ≥ 80 before merge. 3. Optionally gate your source repo with the HOL scanner GitHub Action. Catalog admission uses the centralized scan; source-repo scanner CI is recommended but not required. 4. Ship or submit with confidence

Quick preflight

pipx run plugin-scanner lint .
pipx run plugin-scanner verify .

Scanner Requirements (Mandatory for This List)

All plugins submitted to Awesome Codex Plugins must pass the HOL AI Plugin Scanner:

| Requirement | Threshold | | ------------ | ---------------------------------------------- | | Centralized score | ≥ 80 / 130 | | Source CI | Optional; recommended for pre-submission feedback | | Action status | Advisory when the numeric centralized score is available |

See the full guide: SCANNER_GUIDE.md See contributing requirements: CONTRIBUTING.md

This repo publishes a Codex repo marketplace at .agents/plugins/marketplace.json. The marketplace points at mirrored installable plugin bundles under ./plugins/, so a clone of this repo can act as a curated plugin source in Codex.

Use this marketplace in Codex

Install plugins directly from this curated list by pointing Codex at the repo marketplace:

CLI:

# Add this repo as a marketplace source (one-time setup)
codex plugin marketplace add \
  'https://github.com/hashgraph-online/awesome-codex-plugins.git' \
  --ref 'main' \
  --sparse '.agents/plugins' \
  --sparse 'plugins'
Then browse and install (the marketplace name is derived from the repo name)
codex plugin list --source awesome-codex-plugins
codex plugin install  --source awesome-codex-plugins

Do not use the raw marketplace.json URL with codex plugin marketplace add. The Codex marketplace command clones a Git repository, so a raw GitHub file URL is treated like a repo URL and fails with remote: 404: Not Found.

Desktop App / IDE Extension:

1. Open Codex settings → Plugins → Next to search plugins input click on menu and select → +Add More...

2. Add this URL:

   https://github.com/hashgraph-online/awesome-codex-plugins.git
   

3. The curated plugin list appears as an available marketplace source.

Each plugin entry includes a source.path pointing at a mirrored bundle under ./plugins/ in this repo, so installations are fast and reproducible without hitting upstream repos at install time.
